the IP assignment comes from how it was assigned in the NIC Card
if you have it as DHCP, then we wait for the VM to get an actual DHCP address from the network it is on. eventually we will sync that to the GUI.
if it's static manual, or static ip pool, then it'll be there immediately.
this is just for the GUI.
inside the guest OS, you'd need guest customization enabled for the two static options to actually be applied to the NIC Card present.
